WAAS-Enabled GPS System

WAAS (Wide Area Augmentation System) was developed by the Federal Aviation Administration to augment the Global Positioning System to improve its accuracy, integrity, and availability. WAAS was originally intended to enable aircraft to rely on GPS for all phases of flight, including the precision approach to airport’s within its coverage area. The WAAS system typically provides better than 1.0 meters laterally and 1.5 meters vertically throughout most of the contiguous United States and large parts of Canada and Alaska. This accuracy is capable of provideing aircraft with the precision needed for safe approaches and inflight navigation for all weather conditions. Integrity of the WAAS information is no more than 3 seconds of bad data per year allowing the system to be considerd safe by the FAA for instrument flight rules.

Although orignally developed for aviation, WAAS is not just limited to the aviation industry, any GPS receiver that is capable of receiving the WAAS signal will be able to benefit from it’s correction data, making the GPS positioning more accurate. In fact a WAAS-enabled GPS receiver can even give you directions right down to the lane your car is traveling in (as long as the maping program supports “lane assist” directions). Because the Wide Area Augmentation System is quickly becoming standard in the GPS industry, most new GPS receivers today are WAAS-enabled. Just like with the conventinal GPS, the WAAS system doesn’t come with any extra cost or fees to use. All that is required is that the GPS receiver be WAAS-enabled so it can receive and decode the data then be able to apply corrections to it’s position. Currently the WAAS service is limited to the U.S.A., Canada, Alaska and Hawaii. Although independant from WAAS, Europe and Asia are working on their own supplemental GPS correction systems. Europe has the “Euro Geostationary Navigation Overlay Service” (EGNOS) and Japan is working on their “Multi-Functional Satellite Augmentation System” (MSAS) .  Read more...

Those who are aspiring to have a career in the computer industry, or anyone who desires to have more in-depth knowledge about them for their personal use, needs to look in the direction of computer education. But you will need to identify the area you want to focus on before you enter the fray.

Stuffs called software are the vehicles behind all the wonderful things performed by computers, and some computer education courses are designed solely for teaching people how to use these software. Thus computer education that deals with software will teach you how to use applications like Microsoft Word, PageMaker, Excel, and other programs. As you would have noticed, almost all of the courses have a bias for office work, but you will also be able to learn software that are employed for business purposes, as well as the hugely popular shorthand typing.

Another form of computer education is one that will teach you how the computer itself functions, and if you are interested, about computer programming. Make no mistake about this, this is one of the toughest classes around, but if your desire is to build a career in a lucrative sector, this might be what can propel you to the top. Have you ever asked yourself how the fanciful pages you see on the internet came to be?  Read more...

You’ve probably heard about hybrids at one point or another and how environmentally friendly they are. It refers to a fairly recent class of vehicles which has sparked the interest of many people around the globe. However, what exactly are they and what’s with the name that it dons?

Well first off; these types of vehicles are called hybrids due to the fact that they are fuelled by two distinct kinds of energy. More specifically, these two types of energy are comprised of electricity and conventional gasoline.

To be considered usable in the practical sense, a vehicle must be able to achieve a minimum mileage of 300 miles before refuelling or recharging. The process of refuelling or recharging must also be done in a relatively quick and convenient manner. Lastly, a vehicle must have an average speed comparable to other vehicles out there so as to not obstruct traffic in any way.

Conventional vehicles using gasoline fuel are all capable of conforming to the conditions mentioned above. The only real problem here is the rising cost of gasoline fuel and the fact that such vehicles contribute significantly, to air pollution. On the other hand, electrically powered vehicles are the exact opposite. They produce no pollution once so ever but they are not as fast as other vehicles on the road. Electrically powered vehicles are also capable of impractically low mileage and it generally takes a long time for its batteries to recharge. Hybrid vehicles combine the best of both worlds in an innovative and efficient compromise.  Read more...

Global Positioning Systems (GPS) have been changing the way the world works since its inception as a tool for soldiers during World War Two. Although the design may have been different, the idea of GPS has been around for over half a century.

The design of the GPS is based on similar radio navigation systems, called the Decca Navigator, and were first used in the 1940’s. When the Soviet Union launched the world’s first satellite “Sputnik” in 1957, U.S. scientists discovered that radio transmissions sent from the satellite could be used to pinpoint where the satellite was in relation to the earth. Thus, the idea of the birth of the modern-day version of the GPS was created.

The very first satellite navigation system, which was used by the United States Navy, was tested in 1960. As the technology developed, so too did advancements in locating your position in the world. In the 1970’s, the Omega Navigation System became the first world-wide radio navigation system. It was not until 1978 that an experimental Block-I GPS satellite was launched into space, ushering in a new era for civilian use of GPS. The amount of satellites using GPS’ have increased over the past 30 years, and as a result, many people have benefited from the use of navigation tools used by the GPS.
